By this arrangement the truck frame may This invention relates to railway trucks be very easily assembled or taken apart, as and has for its object the production of a it is necessary only to elevate the bolstersimplified and improved railway truck beam from the frame and remove the plate frame, and particularly such a frame so 13 and the springs 12 in order to replace a arranged as to be not only very effective broken spring or for any other purpose; it and dependable, but also to be easily assembeing unnecessary to remove any bolts. so bled or taken apart when necessary. that with the body of the car removed a few Of the accompanying drawings Fig. 1 is moment's time only is necessary to take a plan view of one side of a truck which apart this portion of the truck. embodies the features of my invention; Fig. The cross-beam 5 may be cast in one solid 2 is an elevation of the truck side; and Fig. piece and it has recesses 20 to receive the 3 is a sectional view along the line 3-3 of bearings 21 of thewheel axle 22. The inner Fi 1. edges of the bearings rest against shoulders The truck comprises the side frames 5 23. and each bearing is prevented from movwhich are connected by-means of the bolstering outwardly by means of a bolt 24. By beam 6 and the strengthening beam 7. The this arrangement the bearings may be easily strengthening beam 7 is rigidly fixed to the removed from the truck by simply removing lower portion of the cross-beams 5. The the bolts 24 and slipping the bearings, with ends of the beam 7 pass through the openthe axle, outwardly. The wheels 25 are ings 8 fitting snugly therein, and are bolted mounted on the axles in an ordinary manner. to the projecting flange 9 of the cross-beam. In order to indicate at all times the weight In this manner the beam 7 may be easily of the car body, which rests upon the bolsterremoved from the cross-beams and at the beams, indicators 27 and scales 28 are prosame time it holds the lower portions of the vided at each end of the truck, the scales beams so as to prevent any tipping tendency indicating pounds or tons as may be desired thereof. The bolster-beam 6 has an suitand the arrangement is such that when the able bolster-ring arrangement 10 in t e cenbody is removed the indexes will point to tral portion thereof, and the ends 11 of the zero, so that the indications of the indexes at bolster-beam are dovetailed into the crossany time will give the actual weight on the beams, the dovetailed connection, however, bolster, by adding up the indications on the being sufliciently loose to allow the ends of various truck ends.

By this arrangement the bolsterthe car, or the mark may become obliterated. beam is free to move vertically in the truck I claim as my invention: frame, and the car body, resting on the A car truck comprising a pair of integral bolster-beams, thus has the advantage of side frames, each frame having an opening the resiliency of the springs. A pin 15, in its central portion, springs mounted in fixed to the end of each bolster-beam, passes said opening, a bolster-beam connecting said through an opening 17 in the plate 13 and frames, the ends of said bolster-beam being 100 slidably mounted vertically by dovetailing of said bolster-beam, with a pin pro'ecting in the respective frames, and a strengthenfrom the end of each of said bolsterearns ing beamconnecting the lower portions of through said plate and through a portion of 10 said frames, the ends of said strengthening one of said springs.
